To all whom it may cqfacem:

` Be it known thatlwe, Connor WILLIAM DoYLn and CHARLES FREDERICK ROTHWELL,

. ycitizens of the United States, and residents tire.

of Columbus, in the county of Stillwater and `State of Montana, have invented new and useful Improvements in Tire-Tools, of which the following is a specification.

ur invention is an improvement in' tire tools, and has for its object to provide mechanism of the-character specified, for use Awithfquick demountable tires, for collapsing the rim r tO permit thev easy' removaly of the Inf-the dra-wings: w "[Figure l is a perspective'v view of a portion of' a rim showing the, manner of using the tool;

OI' the clamps,

i the gripping jaws.`

The p'resent embodiment of; the invention is shown in connection with 'the split ends of a rim 1,"and thel improved tool is cOnnected to the ,rim'on opposite-"sides of the split ,to collapse the same. The tool coinprises a pair of similar clamps, which, are lconnected by a turn buckle. Each of the' "clamps consists of a pair of clamping jaws, -each consisting of a body 2 having at one end a downwardly and" outwardly extending arm 3, which is provided at its free end ,with an inwardly extending. lugs or hook 4L for gripping the edge of the rim. `The body portions 2 of the clamping jaws are cylindrical, and they are received within the cylindrical bore 5 ofl a' gripping jaw 6. This jaw 6 is designed to engage the inner face of the tire, and at its ends" is a series of teeth or corrugations Y, each series consisting of two portions, the portions facing in opposite directions. 4.'Ilebody portions 2 of the clamping jaws are cored, and a coil spring 8 is arranged within 'the' said body portions, each end of the spring being Vconnected with a holding clip or button 9, which engages the outer end of the body portion 2 to hold the spring=in place:v It will be obvious that the spring 'will act to draw the clamping jaws tward each other, to/.cause them to clasp' the One of the clamping jaws is provided-with a loop 'pand or contract the tire.

each' clamp has an upwardly extending lug 11 at its vcenter. These lugs are connected 'by a turn buckle, consisting of the usual donble nut 1,2 and the oppositely threaded rods 13 which are pivoted at their ends to the lugs 1l.

In use, the clamps are engaged with the rim, by grasping the gripping jaw in one hand. The clamps may be engaged by engaging one of the hooks over one edge of the rim, and drawing the other clamping j aw` outwardly, until the hook 4 thereof will engage over the other edge of theA rim. After the clamps are engaged, the nut 12 is'turned, in the proper direction, "toeX- The clamps grasp the rim irmly, and there is no tendency of the sameto loosen under stress.

We claim:

l. A tire rim tool including a turn buckle and its rods, and a pair of clampin members pivotally vconnected to the ro s and Sor ingerpiece 10 for convenience in hanv dling the same, and the gripping jaw of adapted to be secured to-the ends of the l is pivoted, and having at each end a series of gripping teeth, a clamping jaw at each end of the gripping jaw,`ea'ch clamping jaw consisting of a body portion engaging within the bore of the gripping jaw, and a hook for engaging the edgeof the rim, a spring normally drawing the two jaws together, o ne of the said jaws having a handle portion.

2. lin a. tool of the charafcter specified, a clamping member consisting Of a gripping jaw of substantially cylindrical form adapted to extend transversely of a rim, and spring actuated jaws in connection with the gripping jaw for gripping the rim, each of the said clamping jaws consisting of a hook mounted to slide in the gripping jaw,

" and a spring normally drawing the clamp-
